The towing capacity of a 1986 Chevy G30 van equipped with a 350 cubic inch (5.7L) V8 engine generally ranges from 5,000 to 7,000 pounds, depending on the specific configuration and drivetrain options. Factors such as the van's weight, axle ratio, and whether it's equipped with a towing package can influence this capacity. Always consult the owner's manual or manufacturer's specifications for the most accurate towing information.
